Before you begin
The following library is needed to run the
ntservice daemon:
- glibc version 2.5 or later
Root privileges are required to reconfigure, start and stop the
ntservice daemon.
If the system group napatech exists, user access to
ntservice (in effect, any use of SmartNICs with Napatech Link™
Software) requires root privileges or membership of the napatech system
group.
To add the system group
napatech, execute this command:
# groupadd -r napatech
To add
someuser to the
napatech system group, execute this
command:
# usermod -a -G napatech someuser
For each NUMA node it must be possible to allocate 8 Mbytes of memory to be used for
performance measurements. Otherwise ntservice cannot be started.
Steps
To load the driver and start the ntservice daemon:
Procedure
-
To load the driver, execute this command:
# /opt/napatech3/bin/ntload.sh
Note: This step can be omitted, since Step
2 will start by loading the driver, if this has not been done.
-
To start ntservice, execute this command:
# /opt/napatech3/bin/ntstart.sh
To get information about ntstart.sh options, run
/opt/napatech3/bin/ntstart.sh --help.
The --ntpl <file> option applies the NTPL
script in the specified file at start-up.
The <configuration file> parameter allows you to select a
user-defined configuration file instead of
/opt/napatech3/config/ntservice.ini.
The
--option allows you to override and supplement configuration file
settings. The syntax is:
{--option [<section_name>].<setting_name>=<setting_value>}
If omitted, the
<section_name> will be inferred from the
<setting_name> or defaults to
[Adapter0].
Repeat
--option to specify more settings.
-
Optionally, to verify that ntservice is running and to list
installed SmartNICs, run the adapterinfo tool:
$ /opt/napatech3/bin/adapterinfo
